Mosses Ferns Gymnosperms
Do NOT produce flowers
A plant can be divided into 3 parts
Examples of mosses
Moss Spore-producing capsule
Characteristics of Mosses
· Simplest plants
· No true roots, No vascular tissues (no transports)
· Simple stems & leaves
· Have rhizoids for anchorage
· Spores from capsules (wind-dispersal)
· Damp terrestrial land
Ferns
Characteristics of Ferns
· Roots, feathery leaves & underground stems
· Have vascular tissues (transport & support)
· Spore-producing organ on the underside of leaves (reproduction)
· Damp & shady places
Gymnosperms
Pine tree
Needle-shaped leaves
Male cones(in clusters)
Female cones(scattered)
Characteristics of Gymnosperms
· Tall evergreen trees
· Roots, woody stems
· Needle-shaped leaves
· Vascular tissues (transport)
· Cones with reproductive structures
· Naked seeds in female cones
· Dry places
Flowering plants
Monocotyledons Dicotyledons
· Roots, stems, leaves· Vascular tissues (transport)· Flowers, fruits (contains seeds)
Monocotyledons
Parallel veins
Characteristics of Monocotyledons
One seed-leaf
Leaves have parallel veins
Herbaceous plants
E.g. grass, maize
Dicotyledons
Veins in network
Characteristics of dicotyledons
Two seed-leaves
Leaves have veins in network
E.g. trees, sunflower, rose
